IMPEOVED BUTTER-DISH.

Be it known' that I, NATHAN LAWRENCE, of Taunton, of the county of Brist'oLof the State of Massachusetts, have made a new and useful Improvement in ButteiwDishes having semi-spherical rotary covers; and'do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of which i i Figure 1 is a top view, and v Figures 2 and 3 vertical and transversesections of a butter-dishprovideflfwith invention;

- In the drawings, A denotes a vase,'having a sepiifsPhericaIbQdy, a, containing-*a 'seriali-spherical and concentric'cup, B, the two being connected at their edges bye. xler'tior'i,`b,"'of air-annu usf. i strainer, s, for sup. porting the butter, is placed within the cup B. This butter-dish, s'onadeand'supportedhy affootfe, is .provided with ,a rotary semi-sphcrieal hollow cover, C, from opposite sides of which two journalsfcll', extend in opposite directions, they being arranged so that their axes are one hundred and eighty degrees apart. Consequently such journals are in one straight line running diametrically through the cover. Each of such journals termi` nates in a head, o, provided with two wings, e e, and runs through a box or bearing, f, going entirelyuround the journal. The tv vo bearings, ff, are supported in' sockets or ears, gg, eatendingfrom the vase A, each bearing being provided with lips, 7L,to keep it from moving endtvise in its socket. It is kept in the socket by a pin, e', going through it and the Walls of the socket. Within cach head, o, is a chamber, 7c, to receive a helical spring, Z, which encompasses thejournal and bears against the outer end of the bearing f and the outer. end of the chamber lc, such spring serving as a means of producing friction to hold the cover in any position, whether wholly or partially, over the butter-dish.

As o rdnarily made, such butter-vases or dishes have their journals supported in boxes, which are stationary i i or immovable as respects the outer shell or vase, the said boxes being provided with movable caps. I prefer to i make each bex in one block or piece, movable with respect to the vase, and with one end on the journal, because i when so made there is no danger of losing the cap Io i` the box or journal; and, furthermore, I combine with such box and its journal the friction-spring to operate as explained. This friction-spring prevents the cover from suddenly falling back from over the vase, as it is apt4 to do in depositing or moving the vase on a table or otherwise. i

I claim, therefore, the arrangement and combination of the friction-spring with the cover and vase, the journal and the bearing to extend entirely around the said journal, as spcciiied.' i
